IR-derived dust luminosities can help break the degeneracy between these parameters, but IR data are often not available. Here, we explore strategies for SED fitting at z>~1 in the absence of IR data using a sample of log M_*_>10.2 star-forming galaxies from the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS) for which 24{mu}m data are available. We adopt the total IR luminosity (L_TIR_) obtained from 24{mu}m as the "ground truth," which allows us to assess how well it can be recovered (as L_dust_) from UV-optical-NIR SED fitting. We test a variety of dust attenuation models, stellar population synthesis models, metallicity assumptions, and SFHs separately to identify which assumptions maximize the agreement (correlation and linearity) between LTIR and Ldust. We find that a flexible dust attenuation law performs best. For stellar populations, we find that Bruzual & Charlot (2003MNRAS.344.1000B) models are favored over those of Eldridge+ (2017PASA...34...58E). Fixing the stellar metallicity at solar value is preferred to other fixed values or leaving it as a free parameter. For SFHs, we find that minimizing the variability in the recent (<100Myr) SFH improves the agreement with LTIR. Finally, we provide a catalog of galaxy parameters (including M* and SFR) for CANDELS galaxies with logM*>8 and 0.7<z<1.3, obtained using the models we found to be the most robust.2024ApJ...962...59Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/962/59CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/261 : GOODS initial results (Giavalisco+, 2004)J/ApJS/177/431 : Mid-IR sources in EGS (Barmby+, 2008)J/A+A/533/A119 : GOODS-Herschel North and South catalogs (Elbaz+, 2011)J/AJ/141/1 : Spitzer observations of GOODS fields (Teplitz+, 2011)J/ApJ/769/80 : Spitzer/IRAC observations of five deep fields (Ashby+, 2013)J/ApJS/206/10 : CANDELS multiwavelength catalog (Galametz+, 2013)J/ApJS/207/24 : GOODS-S CANDELS multiwavelength catalog (Guo+, 2013)J/ApJS/214/24 : 3D-HST+CANDELS catalog (Skelton+, 2014)J/ApJS/218/33 : Spitzer-CANDELS catalog within 5 deep fields (Ashby+, 2015)J/ApJ/801/97 : GOODS-S & UDS stellar mass cat. from CANDELS (Santini+, 2015)J/ApJS/225/27 : 3D-HST Survey: grism spectra master catalog (Momcheva+, 2016)J/ApJ/827/74 : [NII]/H{alpha} ratio in galaxies with KMOS^3D^ (Wuyts+, 2016)J/ApJS/228/7 : Multi-wavelength data in CANDELS COSMOS field (Nayyeri+, 2017)J/ApJS/229/32 : CANDELS: multiwavelength catalogs in the EGS (Stefanon+, 2017)J/ApJ/859/11 : The GALEX-SDSS-WISE Legacy Catalog 2 (GSWLC-2) (Salim+, 2018)J/ApJS/243/22 : CANDELS/SHARDS multiwavelength cat. in GOODS-N (Barro+, 2019)J/ApJ/890/7 : Environment of gal. in the 5 CANDELS fields (Chartab+, 2020)J/A+A/653/A149 : New-generation dust emission templates (Boquien+, 2021)http://salims.pages.iu.edu/candels/ : CANDELS GALAXY PARAMETERS CATALOG onlinehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/962/59https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/962/59http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/962/59https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/962/59https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/962/59http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/962/59GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/962/59/table4 (CANDELS galaxy parameters catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/962/59/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/962/59/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/962/59/table4?GETtext/xml+votable180.050000true34.27352-5.277460.0055555555555555566/11425 17679 17688 17690 27258 35935https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/962/59?format=asciiUVOpticalInfrareddefaultJ/ApJ/962/59/table4CANDELS galaxy parameters cataloge_logSFR[0.02/3.7] Uncertainty in logSFRlog(solMass.yr**-1)stat.error;phys.SFRfloatAFUV[0.004/8.7] Far-UV reddeningmagphys.absorption;em.UV.100-200nmfloate_AFUV[0.012/4.1] Uncertainty in AFUVmagstat.error;phys.absorption;em.UV.100-200nmfloatAV[0.001/3.5] V-band reddeningmagphys.absorption;em.opt.Vfloate_AV[0.005/1.4] Uncertainty in AVmagstat.error;phys.absorption;em.opt.VfloatlogLd[7.56/12.95] Log of dust luminositylog(solLum)phys.luminosityfloate_logLd[0.02/1.21] Uncertainty in logLdlog(solLum)stat.error;phys.luminosityfloatzbest[0.7/2.5] CANDELS redshiftsrc.redshiftfloatSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
